Rubbish shot for golf, one in the pond? (8)
I believe the answer is:
bullfrog
'one in the pond?' is the definition.
(I know that bullfrogs are often found in ponds)
'rubbish shot for golf' is the wordplay.
'rubbish' becomes 'bull' (both can mean nonsense).
'shot' is an anagram indicator.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'for' with letters rearranged gives 'fro'.
'bull'+'fro'+'g'='BULLFROG'
(Other definitions for bullfrog that I've seen before include "Noisy amphibian" , "Large leaping amphibian" , "Booming croaker" , "Amphibian with deep croak" , "Deep-booming croaker" .)
